Question
(a) What is the length of a simple pendulum that oscillates with a period of 4.0 s on Earth, where the acceleration due to gravity is 9.80 m/s2, and on Mars, where the acceleration due to gravity is 3.70 m/s2?
(b) What mass would you need to suspend from a spring with a force constant of 20 N/m in order for the mass-spring system to oscillate with a period of 4.0 s on Earth, where the acceleration due to gravity is 9.80 m/s2, and on Mars, where the acceleration due to gravity is 3.70 m/s2?
Explanation / Answer
a) Period T = 2pi*sqrt(L/g). Plug in T and g.
b) Period T = 2pi * sqrt(m/k). Plug in T and k. Notice that g doesn't come into it.
